My gmc yukon would not start and the dealer replaced the fuel pump fuse the same thing happen again....where is the fuel pump fuse located
SOURCE: 1997 Gmc yukon fuel relay switch continues to burn out
I would have to check the fuel pump with a scope to look at the pattern and check the amps it is drawing . the grounds need to be checked and the pcm checked and reflashed. on the fuel system that would affect the fuel pump and relay to where it would burn it out is grounds , pcm , fuel pump , fuel pump relay. so you should convince them to replace the fuel pump and fuel pump relay under warranty and replace the pcm . and get a diagram and check all grounds. If the pcm is damaged and the current has been affected and instead of say a 5 volt or 2 volt signal it now has a 13.5 volt signal or if a ground is out then the temp of the relay will keep rising non energized a relay is about 99 energized it is around 140 you can check to see how hot that relay is getting. and if i remember correctly you want the pcm drivers checked.

The fuse is actually a Relay Switch and its located in the Fuse Relay Center on the driverside of the engine compartment. The Black Box is labled Fuse Relay Center, the diagram on the cap displays which Relay is the Fuel Pump relay...the Relay switch is usually $8-$15 depending on where you shop

Check your ECM fuse. There should be 2 fuses for your ECM. It's the ECM that controls the function of the fuel pump. Good luck friend and it's also common for the wire harness from the frame to the fuel pump to go bad due to corrosion from the bad weather we get in the winter and rainy spring and fall.
